I finished the boat assembly on RoCo, including the servo holders and all tabs, and have started trying to cut out a prototype using the paper cutter so we can see if the tabs are strong enough to hold the boat together and if the dimensions of the servo holders are correct. We had some problems fin...

We finished making the 3D boat structure in RoCo. It isn’t perfect because we temporarily hard coded the angles between the faces, but is good enough for the demonstration tomorrow. When we complete the rest of the boat we will go back to the boat structure and figure out the angles to widen the v...

This week we began writing the RoCo code to make the 2D and 3D structures of our boat. So far, we have made one fourth of the boat structure but it isn’t completely correct. The edges of the triangles that make up the bow don’t line up correctly as seen in the 3D model. We think this is due to r...

Boat 7 was created using a template that we made based on the structure of Boat 6. Our goal with this boat was to get an idea of the template we would use in RoCo. We also made new paddle wheels using hexagons instead of circles to simplify construction. Boat 7 was faster and went straighter than Bo...

Boat 4 tested that the pinwheels would work with all the electronics in the boat since our last boat was too small to hold the battery. We also wanted to try making pinwheels with six wings instead of four which turned out to be much more difficult than we imagined. Although this prototype worked,...

Boat 1 Boat 2 Boat 3 Boat 1: Our goal is to create a printable robotic boat for early education. We decided on a paddleboat as the most straightforward model. We wanted to get an idea of how the boat would be constructed with a simple mechanically propelled paddlewheel, so our first prototyp...
